The NTSB's narrative final · quoted from the NTSB record
The flight was on the downwind leg for landing at St. Simons Island when the pilot noticed a gear warning. The pilot elected to divert to Jacksonville. The airplane landed gear up, and came to a stop on an unfoamed runway. An examination of the airplane's landing gear revealed that the left main landing gear failed to extend because the link assembly had jammed against the gear-down lock. It was reported by the FAA that the airplane had just undergone a 5-year landing gear inspection, 22 hours before the accident.
